After the country decided to carry out trials for soil testing and formulating in 200 counties and establish a special fund for soil testing and formula fertilization, the city of Zhengzhou, Henan Province took the lead to implement it. In this year's municipal finance, a special fund of 2 million yuan was set up to guide farmers. Soil Testing Formula Scientific Fertilization "Fertile Soil Engineering". This was the reporter's interview on July 26 from the city's soil and fertilizer station.

It is understood that in the spring of this year, the Ministry of Agriculture set off a test soil fertilization program in the country. Since then, the Ministry of Agriculture and the Ministry of Finance have jointly decided to set up a special national financial subsidy for soil testing and formula fertilization for pilot soil testing and formula fertilization in 200 counties nationwide. The “fertile soil project” in Zhengzhou City began under this background.

As one of the major grain production areas in China, the goal of the “fertile soil project” in Zhengzhou is to increase the land fertility of Zhengzhou city by one to five years from the beginning of this year, increase the utilization rate of fertilizer by 5 percentage points, and cultivate land per unit area. Crop production increased by 10%. The entire project was implemented in three phases. The first was the survey of cultivated land fertility in Zhengzhou City in 2005, the establishment of soil fertility monitoring sites and soil moisture monitoring sites, and the improvement of municipal soil and fertilizer laboratories; the second was on the basis of surveys and laboratory tests in 2006. Establish a database of cultivated land fertility in Zhengzhou, and produce electronic maps of cultivated land fertility to guide farmers to apply chemical fertilizers scientifically and reasonably; Third, actively promote the comprehensive utilization and harmless treatment of organic fertilizers, encourage and support the development of commodity organic fertilizers and organic inorganic fertilizers Compound fertilizers and other new types of fertilizers will guide farmers to apply more organic fertilizers, increase soil organic matter, reform traditional methods of cultivation, and develop conservation tillage to achieve sustainable agricultural development.

It is understood that another prominent feature of Zhengzhou City's "fertile soil project" is the close combination of soil testing formula and fertilizer production. After obtaining monitoring results such as soil fertility characteristics, Zhengzhou City will establish a soil fertility database and publish it free of charge. Fertilizer production enterprises can obtain the local fertility conditions in Zhengzhou on the Internet, and they can directly contact the Zhengzhou Soil Fertilizer Station to engage in joint ventures and jointly produce formula fertilizers. At the same time, not only chemical fertilizer companies in Henan can enjoy this huge wealth, but also fertilizer manufacturers outside the province can produce fertilizer based on these data to meet the farmers' farming needs in Zhengzhou.
